Meat grinder

Abstract

Disclosed is a meat grinder. According to the technical solution of this disclosure, food is placed into a processing cavity through a material inlet, and after the food is fallen to a side of a propeller away from a cutter head, the propeller is configure to propel the food to a cutter. The food is pressed against the cutter head and the food on the cutter head is cut by the cutter, and the food in discharge holes is squeeze outed by the propeller. Because the propeller is rotatably connected to the cutter head through the wear part, it may prevent an end of the propeller facing the cutter head from rubbing directly against the cutter head and causing black powder, so as to avoid the risk of contamination of the meat and affect the user's experience.

What is claimed is: 
     
       1. A meat grinder, comprising:
 a housing, defining a processing cavity inside, a material inlet on a side wall, and a through opening at an end in a longitudinal direction, the through opening being in communication with the processing cavity; 
 a cutter head, covering on the through opening and defining discharge holes and a positioning hole, the discharge holes being in communication with the processing cavity; 
 a wear part, arranged in the positioning hole; 
 a propeller, arranged in the processing cavity, one end of the propeller being rotatably arranged on the wear part, the other end of the propeller being rotatably arranged on the housing, the material inlet being located on a propulsion path of the propeller; and 
 a cutter, arranged on an end of the propeller facing the wear part, 
 wherein the propeller comprises: 
 a spindle, one end of the spindle being rotatably arranged on the wear part, the other end of the spindle being rotatably arranged on the housing; and 
 a spiral member, surrounding the spindle; 
 wherein, food is entered in the processing cavity through the material inlet, fallen to a side of the spindle away from the wear part, and propelled toward the cutter by the spiral member when the spindle rotates, 
 wherein the cutter comprises: 
 a cutter body, defining a central hole, an end of the spindle facing the wear part being arranged in the central hole, extended to an outside of the central hole, and rotatably connected to the positioning hole; and 
 blades, integrally formed or detachably arranged on an edge of the cutter bod, 
 wherein the cutter body defines an avoiding notch at a side facing the cutter head, and an end of the wear part facing the cutter is attached to a side wall of the avoiding notch facing the cutter head. 
 
     
     
       2. The meat grinder of  claim 1 , wherein a surface of a side of the blades facing the cutter head is parallel to the side wall of the avoiding notch facing the cutter head. 
     
     
       3. The meat grinder of  claim 2 , wherein a side of the spindle facing the cutter head is provided with a special-shaped structure adapted to the central hole. 
     
     
       4. The meat grinder of  claim 3 , wherein an end of the special-shaped structure facing the cutter head is smaller than the side wall of the avoiding notch facing the cutter head. 
     
     
       5. The meat grinder of  claim 3 , wherein an end surface of an end of the special-shaped structure facing the cutter head is lower than or flush with the side wall of the avoiding notch facing the cutter head in an axial direction. 
     
     
       6. The meat grinder of  claim 3 , wherein a thickness of the special-shaped structure in an axial direction is smaller than or equal to a length of the central hole of the cutter body. 
     
     
       7. The meat grinder of  claim 1 , wherein a distance between a peripheral wall of an end of the spindle facing the cutter head and a hole wall of the central hole of the wear part is 0 to 0.2 mm. 
     
     
       8. The meat grinder of  claim 1 , wherein the wear part is detachably connected to the positioning hole of the cutter head; or
 the cutter head and the wear part are integrally formed. 
 
     
     
       9. The meat grinder of  claim 1 , wherein an end of the propeller away from the cutter head is penetrated through the housing and is extended to form a transmission part in transmission connection with an external driving part.
